Okay Aspiring mathematicians here go more drills for you You've

00:05

got this thing here Point four times fifteen plus two

00:08

divided by two minus quantity and negative a third time

00:11

Say twenty one is equivalent to which of the following

00:19

well we got to simplify this thing here This is

00:21

clearly a pym dos thing And yes when we first

00:24

heard of pim das we were really hoping for a

00:26

cool hybrid panda leamer creature or something Imagine our disappointment

00:31

when we discovered some nonsense about someone's dear aunt sally

00:34

and the order of operations right Parentheses exponents multiplication division

00:39

addition and subtraction Yeah that's pym das And it requires

00:42

us to begin with multiplication and division So let's put

00:44

two terms that are being multiplied in Prince sees eh

00:46

So we're doubly reminded Tio start with those first Yes

00:50

put him up there We should do the same for

00:52

the two terms with a division signed between them Then

00:55

we deal with what's in our three different sets of

00:58

princess easier Right So it's going to look like this

01:00

All right here's the original problem and we're going toe

01:03

simplify this thing We got pulling four times fifteen ryan

01:06

to divide by two forgetting things here What does that

01:08

give us Well that's six plus one on a negative

01:13

third time Twenty one there What is that Minus seven

01:16

Okay so six plus one minus heaven Fancy subtraction here

01:20

From left to right Seven minus seven is what Fourteen

01:23

No Zero Yeah it seems like an awfully roundabout way

01:27

of writing in zero there But who are we to

01:29

judge the answer's c zero
